Kim Yong Nam, the 90-year-old head of the North’s parliament, will lead a 22-person delegation to South Korea for a three-day trip starting Friday, according to Reuters, citing North Korea’s official KCNA news agency and Seoul’s Unification Ministry.

News of the visit has sparked speculation about possible talks between the two adversarial Koreas, and potentially even the United States, during the games.

Kim’s visit “shows North Korea’s resolve for improved inter-Korean relations and the success of the Olympics, as well as its sincere, earnest attitude,” Kim Eui-kyeom, spokesman for the South’s presidential Blue House, told reporters on Monday, per Reuters.

U.S. Vice President Mike Pence, who also plans to attend the opening ceremony in Pyeongchang, has reportedly expressed less optimism about North Korea’s appearance.

“The vice president will remind the world that everything the North Koreans do at the Olympics is a charade to cover up the fact that they are the most tyrannical and oppressive regime on the planet,” the aide was quoted as saying. “At every opportunity, the VP will point out the reality of the oppression in North Korea by a regime that has enslaved its people. We will not allow North Korea’s propaganda to hijack the messaging of the Olympics.”
